How long will those tanks last you? In Joburg my gardener will empty my 2kl in 45 minutes with the pump running....Yep, ours too. A 100m^2 roof with 25mm of rain equals 2500 liters!
Gotta watch those interconnection and overflow pipes, particularly when there is heavy rainfall. Running water can undermine the tanks, and do quite a lot of damage...
I find it ironic that all the tanks are now full, just when our garden doesn't need any watering...
